WOVEN DOUBLE-PILE FABRIC.

SPECIFICATION forming part of Letters Patent N0."l,573, dated June 3, 1902. Application filed eptembel 21, 1901. Serial N0. 76|06L (No model.)

To all whom, it may concern:

Beit known that I, JOHN KILLARS, a citizen of the United States, residing in Stonington, in the county of New London and State of- Connecticut, have invented certain new and useful Improvements in Woven Double-Pile Fabrics, of which the following is a specification.

This invention relates to improvements in double-pile fabrics, and more particularly to that class of velvets known as croiss velvets; and it consists in the weave and construction of the pile fabric, as is fully described hereinafter.

The object of my invention is to provide a double-pile fabric having an even surface,in which by the same number of picks double the number of pile warp-threads is looped in with the ground warp and filling threads of the top and bottom pieces, so that a pile fabric with a fuller body, which is due to the increased number of pile tufts, is obtained without any pile marks or ridges appearing on thegoods.

For this purpose the invention consists of a pile fabric composed of ground warp-threads, filling-threads, and pile-tufts arranged independently of each other in pairs upon successive pairs of filling-threads, one tuft upon each thread, and said pairs arranged in staggered relation between the successive'ground warp-threads.

The invention consists, further, of the dou ble-pile fabric, as hereinafter described, and defined in the claims. Y

In the accompanying drawings, Figure 1 represents a diagram showing a plan view of a portion of my improved pile fabric, taken from the bottom piece, showing the ground Warp and filling threads separated and the tufts of pile-threads l0oped alternately between the same. Figs. 2 and 3 are respectively vertical longitudinal sections on lines 2 2 and 3 3, Fig. 1. Figs. 4 and 5 are diagrams showing the looping of the pile warpthreads alternately with the ground warp and filling threads, and Fig. 6 is a diagram showing the drawing in of the'warp-threads into the harness.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, w w w to represent the ground warp-threads, of which'w and to form the warps for the bottom piece, and w and w the warps for the top piece. f represents the filling-threads for the bottom piece, and f the filling-threads for the top piece, which filling-threads are interwoven with the ground warp-threads of the top and bottom pieces in the usual manner.

P P P P are the pile warp-threads,which are located -in'termediately between the ground warp-threads in the harness.

The double-pile loom upon which my improved fabric is made is of any approved construction and provided with two shuttles that are thrown at the same time, one for the shed of the top piece and the other for the shed of the bottom piece. Each pile Warp-thread forms for every two sheds a pile-loop, each pile-loop thus obtained crossing the adjacent ground warp-threads, so that by the same number of picks double the number of pile loops is formed. The fabric is woven in a double pile, four ground warp-threads and four pile warp-threads being used for each repeat of theweave. The four pile warpthreads, two in each dent, loop alternately for every pick in the top and bottom piece and cross each time with one adjacent ground warp-thread, so that every loop from the same pile warp-thread repeats only after four picks,

thus preventing the pile from looping upon the back of the goods, which would happen if only two pile-threads were used instead of four and'were'looped over every other pick. By this weave double the number of pileloops are made with the same number of picks and filling-threads as compared with the double-pile weaves heretofore in use.

Figs. 4 and 5 illustrate the alternating reedopenings, while Figs. 2 and 3 sho w the alternating arrangement of the two'sets of pile-tufts after the severanceof the pile warp-threads. The pile-tufts are arranged in pairs uponsucce'ssive pairs of filling-threads in staggered relation between the ground warp-threads, each pair of tufts entirely beyond-4'. e., out of line with and not overlapping-the adjacent pairs of tufts. V

In drawing the warp-threads into the harness the warps w are drawn into separate eyes in the harness for the ground-warp of the bottom piece, the warps into the harness.

for the top piece, the warps w into the harness for the bottom piece, and the warps 10 into the harness for the top piece, as shown in Fig.6. Warp-threads? P are in one dentopening with the ground warp-threads w w while the pile warp-threads P P are in the same dent-opening with the ground warpthreads 10 uh.

By the first pick the filling-thread in the top piece goes under pile warp-thread P, over ground warp-thread 10 and under ground warp-thread At the same time the fillingthread passes in the bottom piece over pile warp-thread P over ground warp-thread w, and under ground warp-thread 10 The pile Warp-threads P and P are in the middle between the top and bottom pieces. By the second pick in the top piece the filling-thread goes under pile warp-thread P over ground warpthread 10 and under ground warp-thread 10. In the bottom piece it goes over the pile warpthread P over the ground warp-thread w, and under the ground Warp-thread 10 pile warp-threads P and P being in the middle. With the third pick in the top piece the filling-thread goes under pile warp-thread P over ground warp-thread w,and under ground warp-thread w". In the bottom piece it goes over the pile warp-thread P, over the ground warp-thread Q0 and under the ground warpthread w. The pile warp-threads I and P remain in the middle. WVith the fourth pick in the top piece the filling-thread goes under the pile warp-thread P over the ground warp thread 20, and under the ground warp-thread 10 In the bottom piece it passes over the pile warp-thread P over the ground warpthread w, and under the ground warp-thread w. The pile warp-threads P and I are in the middle. Then the same picks are repeated again for next weave, and so on.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A pile fabric composed of ground warpthreads, filling-threads, and pile-tufts arranged independently of each other in pairs upon successive pairs of filling-threads, one tuft upon each thread,and said pairs arranged in staggered relation between the successive ground warp threads, substantially as set forth.

2. A double-pile fabric, consisting of upper ground warp-threads, lower ground warpthreads, upper filling-threads, lower fillingthreads, and pile warp-threads, two to each ground warp-thread, arranged between the same, said pile warp-threads being looped in pairs upon successive pairs of filling-threads alternately in the top and bottom pieces, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

JOHN KILLARS.
